I’ve been thinking about it for days, but the realistic use cases for an outdoor plug-in dimmer continue to elude me. Outdoor on / off sockets and switches, safe. An outdoor intensity regulator? Probably a niche situation. I guess if the party lights on your string are just too bright to set the mood, well maybe a dimmer makes sense. You are the judge.
TP-Link’s Kasa Smart KP405 is a single outlet dimmer that is otherwise identical to the company’s single outlet outdoor plug, the model KP401. The all-black IP64-rated device has the common pigtail design, a rubber outlet cap (on the loose side, just like other recently released Kasa products), and a power button on top. A green LED indicates whether the power is on or off; this can be disabled in the Kasa Smart app.
Please note that the physical power button cannot be used to dim / brighten. It is strictly an on / off switch; all dimming functions are exclusively available in the app. The maximum power supported is 300 watts for incandescent lighting or 150 watts for LED lighting.

The setup is identical to other Kasa Smart products, requiring you to connect to a temporary network and connect to your own 2.4 GHz Wi-Fi network. (As with other Kasa Smart outdoor products, TP-Link promises 300 feet of range).
The setup was relatively quiet in my tests, but I found the unit to be surprisingly slow to respond to commands, sometimes taking up to 10 seconds to turn on or off or change the brightness; thankfully, he never completely abandoned his connection. At other times he responded almost immediately.
The power and dimming functions are confusingly found on separate panels within the Kasa Smart app, although there are a few presets available on the main panel that make it easy to access commonly used brightness settings. These are easy and intuitive to change, just wondering why all of this could not be achieved in a single panel. A simple scheduling and timer system is included, as well as a random vacation mode; Amazon Alexa and the Google Assistant are supported if you want more granular control over multiple devices and voice support.
It’s a good product, but even if you sell the Kasa Smart brand, the only reason to consider the KP405 is if you need dimming features, and you don’t need more than one outlet where you are. install it. If you don’t need an outdoor dimmer but have other Kasa Smart products and want to control them in a single app, both the single outlet Kasa Smart KP401 (a smart on / off plug) and the somewhat older Kasa Smart EP40 (a smart plug dual output on / off switch with independent control) costs less, but neither supports dimming.
If you don’t mind toning down Y You don’t mind using another app, consider Wyze Plug Outdoor from Wyze Labs. It’s our current top pick in outdoor smart on / off plugs, and it was selling for $ 12 less than the Kasa smart dimmer you use. That said, the dimming features are unusual for an outdoor smart plug. If that’s a must-have feature, this Kasa Smart KP405 is good value for money.
